Interfering with the CD279(PD-1) – CD274(PD-L1) axis has shown great promise in restoring anti-cancer T cell function.  This Pittsburgh research group has used a similar approach in a mouse HSV-1 model to improve T cell mediated viral clearance from the immunologically sequestered cornea.   “PD-L1/B7-H1 Inhibits Viral Clearance by Macrophages in HSV-1–Infected Corneas” Sohyun Jeon, […]

ANC28.1 mAb used as a Control in a Modified Chandler-loop model developed to screen and assess drug toxicity This system could potentially prevent disastrous clinical human trials like the TGN1412 (anti-CD28) one.   “Extracorporeal human whole blood in motion as a tool to predict first-infusion reactions and mechanism-of-action of immunotherapeutics”  E A K Fletcher, S

In CD28 knockout mice, TFR cells have diminished suppressive ability, and B cells cause systemic inflammation. “B Cells Drive Autoimmunity in Mice with CD28-Deficient Regulatory T Cells” Ruan Zhang, Laurence A. Turka, et al J Immunol December 15, 2017, 199 (12) 3972-3980; DOI: https://doi.org/10.4049/jimmunol.1700409

CD244 (NK cell Activation Inducing Ligand, NAIL, NKCR 2B4, Nmtk) is a member of the Signaling Lymphocyte Activation Molecule (SLAM) family, which also includes CD2. It is expressed on NK cells as well as a sub set of T cells.  The type of signaling is controlled by the prevalence and type of intracellular adaptor proteins.

New Ancell TIGIT-muIg binds to CD155 on U-937 cells and to recombinant CD155-muIg in EIA!   The TIGIT – CD155 regulatory pathway is emerging as an important element of immune function.  Studies using knockout mice demonstrate that this pathway is important in optimal NK effector cell function (activation and/or tolerance) (1) There is significant potential

The CD47 – along with its ligand, SIRP alpha are now recognized as an important  regulatory element of innate immune function.  (1).  CD47 is described as a “don’t eat me” signal. However, it appears that CD47, along with Intraflagellar Transport Proteins 20 and 57 (IFT 20, IFT 57) are also involved in T cell receptor

CD268 (BAFF-R, TNFRSF13C) is a significant marker for B Cell Precursor Acute Lymphoblastic Leukemia (BCP-ALL). Ancell clone ANC268.2 was used to phenotype patient samples.  Blocking the BAFF – BAFFR pathway may prove to be useful in treating BCP-ALL.  “TNFRSF13C (BAFFR) positive blasts persist after early treatment and at relapse in childhood B-cell precursor acute lymphoblastic
